Freeport, Texas, is built on a growing delta at the mouth of the Brazos River. The land on which Freeport is built continues to grow because the Brazos River –

• deposits new material on the delta

• removes sediments from the delta

• moves farther away from the delta

• receives fresh water from the delta

• Solar Radiation
• The Earths Core
• Fire
• Hard Work

How can energy play a role in different rock types forming?

• Energy from different sources leads to different types of rock. Energy inside Earth melts rock into liquid rock, but energy from the sun causes rock to weather into small pieces of rock.

• Energy causes different types of rock to change in different ways. Energy changes igneous rock into liquid rock and changes sedimentary rock into small pieces of rock.

• Energy changes rock on different continents in different ways. Each continent on Earth on Earth has different rock that might form liquid rock or small pieces when exposed to energy.

• Energy caused one rock type to form, but not the other. Rock that forms because of energy is a different type of rock than rock that forms without energy.
